Title: A method for repeaters to adaptively digitally code received analog information
Inventor: BENNETT RICHARD LIONEL
IPC: H04B1/40
Filed: 1994-01-27
Abstract: Adaptive digital coding of received analog information based on signal strength can be accomplished in the following manner. Once a repeater receives analog information from a communication unit (200), the signal quality of the received analog information is determined (201, 203). Next, the signal quality of the received analog information is compared with a first signal quality value (204). If the signal quality of the received analog information is above the first signal quality value, the received analog information is digitally coded based on a first digital coding format (208). If the signal quality of the received analog information is below the first signal quality value, the received analog information is digitally coded based on a second digital coding means (206).

Title: System and method for fast huffman decoding
Inventor: KEITH MICHAEL
IPC: H03M7/40
Filed: 1994-05-12
Abstract: Abstract A method is provided for performing statistical decod-ing if a symbol in a data stream having byte boundaries wherein the symbol may have varying alignments with respect to the byte boundaries.  The next byte of data is fetched from the data stream wherein the fetched byte contains at least a portion of the symbol.  Based on this byte and on the current bit position, which is maintained by a state machine, either (a) a decoded value is obtained from a lookup table, or (b) further bytes are fetched and used to determine the decoded value.  Each symbol has a prefix and free bits wherein the entire symbol may be included in the next byte, a boundary of the next byte may fall within a prefix, or a boundary of the next byte may fall within the free bits depending on the alignment of the symbol.  Differing action routines, corresponding to differing symbols, may be selected for execution according to the decoded values determined in the symbols.

Abstract: A tree treatment capsule is disclosed as including a plastic container (10) having a shank (11) with an internal cavity (14) for containing therein a chemical agent (2) and a head (12) integrally formed with the shank portion (11). According to a first embodiment, the shank has a plurality of scorings (20) which are formed in the exterior surface thereof and extend lengthwise of the shank. The scorings (20) allow the shank (11) to be broken so that when an impact force is applied to the head to move the shank towards the plastic plug (30), the plastic plug (30) expands and breaks the shank (11) along the scorings (20) into tongues to form slits between the tongues. According to a second embodiment, the plastic plug (30) is provided to sealingly close the cavity. The shank has a plurality of slots (20A) which are formed in the exterior surface thereof and extend lengthwise of the shank. The slots allow the shank to be broken so that when an impact force is applied to the head to move the heads towards the plastic plug, the plastic plug expands and breaks the shank along the slots into strips to form passages between the strips. The slits or passages allow the chemical agent to pass from the cavity of the capsule through the passages and mix with sap of the tree.

Abstract: The docking assembly comprises a plug 1 formed at the proximal end 2 of the guidewire 3, and a socket formed of a tubing 4 permanently bent so as to have a V shaped portion 5 comprised between two straight portions 6 and 7. The end of straight portion 7 is affixed to the distal end of extension wire 9. A sleeve 10 is slidably engaged over the tubing 4 to substantially straighten it and facilitate insertion of plug 1 into the tubing. Removal of sleeve 10 allows the tubing to recover its preshaped deformation, thereby assuring locking of plug 1 in tubing 4. To release the assembly it suffices to pull the guidewire and extension wire oppositely to slip the plug 1 out from the tubing 4. <MATH>

Patent CA-2149383-A1 (CA)
Title: Optical fiber gripping and positioning apparatus
Inventor: EVANS DAVID C
IPC: G02B6/46
Filed: 1995-05-15
Abstract: The apparatus uses a gripper mounted on a moveable arm to pick up an optical fiber at a pickup location, with the free end of the optical fiber extending from the gripper. The arm is moved to position the free end generally in the region of the target location, but slightly displaced therefrom. An image of the region of the target location is obtained from a camera directed to receive the image, where the region is backlit by diffused light from a light source. Where the target is a component on a translucent substrate, the substrate may act as the diffuser for the light source. The image from the camera is analyzed to determine the position ofthe free end in relation to the target location, and the arm is moved to accurately position the free end at the target location based on the determination of relative positions. The gripper has a downwardly-opening inverted V-shaped groove runninglongitudinally, to which a vacuum is supplied.
